started @bolna_dev to build for india's voice AI.

somehow that led to convincing an entire industry to meet in person lol.

symphony. 20 november. bengaluru.

if you're building in voice AI, come meet the people you've only known as API endpoints.

everything starts with users. the closer you are - the better. a lot of our core features have been built, have evolved & been improved due to their constant feedback.

founders or folks starting to build something “they like” seldom works out.

“make something people want”

I am nearly 4+ Months In WhatsApp

I think of WhatsApp like a shared language, spoken by 3bn+ people. Sometimes we use words, and sometimes it’s a voice note to a parent, a sticker that ends an argument, or a "that was a fun dinner” at the end of the night. Language is at the heart of everything we as people do. We write letters, tell stories, get things done and make plans for the future. A WhatsApp chat is often where we start. 

Like any language, the people who use it shape it. They don't wait for permission. They find new things to say, and new ways to say them. Often, our users show us what should come next based on how they’re using the app and communicating in the world. 

I’ve spent the last few months listening and understanding what our users want from us and what I heard is simple: help people stay close to those who matter to them, and get more done on WhatsApp. So that's what we'll build.

First, we want to make connections richer.

Sometimes hearing someone's voice, sending a joke, agreeing on a plan or knowing they're safe is the whole point. People send over 10 billion voice messages and over 4 billion stickers on WhatsApp every day. As the way people communicate evolves, we will evolve these experiences with them. We'll make voice notes, groups, stickers and video simpler and more expressive, because how people feel close keeps changing.

Second, we want anything you do on WhatsApp to be as simple as sending a message. Too many things start in a chat and end with many more steps somewhere else: paying a bill, borrowing money, staying connected when you travel. Each handoff to another task costs time. We're working with financial services and telecom partners so that finishing something feels as easy as starting it.

Third, we want to make this all more efficient with AI. It should quietly find what you need, get things done and make sure you never miss a booking or an appointment. The best technology saves you time, so you can get back to the connections that matter.

None of this works without trust. WhatsApp handles over 100 billion messages and 2 billion calls every day. Trust takes years to earn and a moment to lose, and I don't take that lightly. Whatever we build, WhatsApp must remain simple, reliable and private. These principles we’ve had for years aren’t changing. Your personal messages and calls stay end-to-end encrypted. This and our quality bar stays the same.
What happens inside WhatsApp only matters for what it makes possible outside it: more time together, stronger communities, and fewer barriers between people and the lives they want to live.

Onwards.
